hi i am using stm32mp157caa3, there is a i2c slave operating at 3v3, while design, we have not connected( "forget")pull up line on i2c clk and data line, so i tried enabling open-drain internal pull up in dtsi , but i2cdetect is not able to find the ...
I am facing a freeze on M4 and A7 core when enabling FreeRTOS with OpenAMP_TTY_echo example.Can someone please point out if OpenAMP and FreeRTOS can be run together or not?
I want to use i2c-2 and i2c-6 from the user space to access different external devices. With 'i2cdetect -l' I can see the interfaces, But executing 'i2cdetect 3' sais 'Bus busy'.Used HW: Phytec Sabre Board (phyBOARD-Sargas)Linux: Yocto-OpenSTLinux PD...
Previous kernel versions had support for the STM32MP1 internal temp sensor. See:stm32mp1-adc-temp definition in stm32mp157c device treeDT bindings documentationApparently this has been removed in later kernels. Isn't this supported anymore ?Thanks,Gu...
Hello STM Community,I am following the workshop STM32Cube.AI workshop with my STM32MP157C-EV1 https://www.youtube.com/watch?v=k8AAr84z27s&list=PLnMKNibPkDnEOUdTXlDH7yWN6qyxXPsEb&index=9&t=8m15s When I analyze the model I get the error "Required Ram o...
Hello all, I managed to enter the DFU mode by rebooting the SoC from the command line after setting the proper tamper register to get the Uboot to select my desired USB boot mode. After flashing the new image with the STM32CubeProgrammer I would li...
